The disks 69, 70, are also provided with peripheral flanges 74, 75, for guiding the web X over the roller etal., but as shown 'at 7 6, 77 (Fig. 1), these flanges are omitted adjacent. the brushes 42, 13, to prevent the coating solution from being deposited on them by the brushes. The chainbers 78, 79, ofthe disks 69, 70, communicate, as at 80, 81, with an air channel 82, extending through the spindle 5S from one of its ends, as 83, Which is adapted for 'connection with a suitable source of supply of cour pressed air, as by having a valveveoupling 84 for a. flexible hose (not shown) attached thereto.

A series yof nipples 85, with the air chambers 7S, 79, of the disks (59, 70, are mounted in the periphery of the disks adjacent the brushes 42', 43. ',lhese 'nipples register with the sprocket apertures :1; of the web X as it passes over the roller '44 in coutaet With the brushes i2, 43,'i1nd direct jets of air through these sprocket apertures to A' prevent the apertures from being' bridged over by the coating solution, and to prevent any of the solution from l'iassing through the apertures to the back ot' the web.

Inorder that the amount of the solution carried out of the pans 18, 1f), by the feed rolls 39, 4() and 41, may be adjustably regulated, Vanes 86, which Wipe the these rollers, are provided. (hie of these vvenes is illustrated in detail in Fig. 7 et the drawings. As there shown it is carried by a spindle 87, which` extends across the traine 14 and is journaled in the side members 15, 16, of the frame. Means are provided tor angularly. adjusting` the spindle 87 to cause the free edge ot' the vane 86 to bear with more or less force upon the periphery ot the ladjacent feed roll. To this end a worin Wheel 88 is mounted upon one end of the spindle, and a Worin shaft 89, rotatablymounted in a bracket 90 secured to the adjacent sidenieniber of the frame and havingra knurlcd head 91, cooperates with the worin wheel 8S. rlhe vanes 8V provided for wiping the periphery of the feed rolls i0 and 41, are identical in construction with that provided for wiping the periphery of the feed roll 3i), and shown lin detail in Fig. 7 of the drawi except that the corresponding spindles 3 and worin shafts 89 are carried by the bracki'at-arnis 53, 54. as shown in Fig. 1, instead ol.i by .the fraine members 15, 1G.

Means `are also desirably provided for wiping the coating' solution troni "the sides of the feed rolls 39, 4() and 4.1. For this purpose yielding angulady-adjustable vanes mounted on the side walls of the pans, as 18 (Figs. 3and 7), for bearing upon the sides of tli'ieed rolls, as 39. As

communica ting `adjacent side tace periphery of,

shown, each ot' these vanes is Vl'ornie'd of sheet metal, having' its lower edge downwardly curved into the pan, as at 91 (Fig. 3), and is carried by hinge otally mounted upon the edge oi thepan. Preferably the bas-'e of each of the hinge brackets 95 is Vinade angular, as shown at 9G, 97, 9S (Fig. 3), and a leaf spring Sii). eX- tendingv along thcedge ot the pan, bears upon the a lig'ular hase ot' the hinge bracket: to cause the vane to yieldinggjly engage the. ot' the feed rolhas shown by full lines in Fig'. 3, or to support thevane in the upright position shown by dotted desired to remove lines in Fig'. 3 when it is the feed roll troni the pan. A

ln beginning' the operation ot the machine the end ot a web X carried by the reel A is drawn through the machine, either by hander by attaching' it to the end oi a web which has preceded it, until a sutlicient lel'lgth has been drawn out to reach the traveling' dryin; rape l.l The end ot thc web is then attached-lo the drying' tape il. and the movement; or the tape causes the web to be continuously drawn through the inachinc. Movenici'it ol the webbing' over thc sprocket roller #le causes a rotation ot' the feed roll 39, which by constantly dipping in the solution contained in the pau 1 an initial coating ot' the solution Vto the far-o ot' the web. v

The 'feed rolls l() and 4l. and brushes i2 and 4?), are cmitiuuous'ly rotated by ineans of' power appl i to the driving pulley (35E. The rotation oi the brushes 2l-2. 5%. causes them to he i'onlinuously supplied with coating selulion delircrcd lo theni from the pan, 1!) by the teed rollsl lll and 4I. and this solution ,may in turn be applied lo the 'tace ol' the web X, giving' it a smooth coating'. Alt the nipple elv be connected to a suitable supply oi compressi-al air, air jets will constantly issue from" the nozzles 853, and in passingthrough the sprocket apertures n: oi ot' the web X as these apertures pass in 'liront ot the nozzles during' the turning' oiE the web over the supporting' roller i4, accumulation oi. the coatingl solution iu the sl'nfocket apertures fill be prevented. lution delivered to the web X by the gleed Yroll 39, and deli rered to the brushes 42, fill,

As the bracket arms 53, 5e, swing'about the shaft 55 which carries the driving gear (SLL, as a center, the adjustment of thefeed rolls 4:0 Vand il does not interfere with the engagement between the gears 65, 66, and the driving gear G4. The degree of force With which the brushes 42, 43, bear upon the surface of the web X as it turns over the roller ,44, may be adjusted by a use of the' setscrews 62, Which determine the elevation 'at which the bracket arms 59, 60, are sup ported.

` The machine asorganized will eii'ectually apply a solution of pyroxylin to the gelatin surface of a moving picture machie film, thereby causing the gelatin to be protected upon both sides by a web of substantially the same character. The various parts of the machine are so disposed that they are conveniently accessible for cleaning and Jfor renewal and repair.
